The array antenna comprises a plurality of linear arrays, uplink-downlink duplexers, and beam-forming networks. Each linear array is a dual-polarized linear array. An input end of the beam-forming network is coupled with a downlink signal output end of a RF (Radio Frequency) unit, and two output ends of the beam-forming network are respectively coupled with downlink signal transmitting ends of two uplink-downlink duplexers; transceiving ends shared by two uplink-downlink duplexers are respectively coupled with arrays having the same polarization direction of two adjacent linear arrays, and the two arrays having the same polarization direction form a beam with 65-degree beamwidth on the downlink through the beam-forming network; uplink signal output ends of the two uplink-downlink duplexers are coupled with uplink signal input ends of the RF unit; linear arrays uncoupled with uplink-downlink duplexers in the plurality of linear arrays are all coupled with the uplink signal input ends of the RF unit respectively. Thereby, a beam with 65-degree beamwidth may be formed by a transmitting antenna on a downlink."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Array antenna and base station","description":"An array antenna and a base station are provided.
